RISNumerical Simulation of Indirect Tensile Test Based on the Microstructure of Asphalt Mixture
Publisher: American Society of Civil Engineers
Abstract: Indirect tensile (IDT) test is widely adopted to evaluate the anticracking performance of hot-mixture asphalt (HMA) at intermediate and low temperatures. This paper presented an approach to simulate the IDT test based on ...
Modification Mechanism of Using Waste Wood–Based Bio-Oil to Modify Petroleum Asphalt
Publisher: ASCE
Abstract: The aim of this research is using a waste wood–based bio-oil as the modifier of petroleum asphalt and analyzing its modification mechanism. The four components, infrared spectrum, and molecular weight distribution analysis ...
Microscopic Analysis of Aging Effects on the Adhesion Properties between Asphalt and Mineral Aggregate
Publisher: American Society of Civil Engineers
Abstract: This research investigated the effect of aging on the adhesion properties between asphalt and aggregate at the molecular level. Based on the molecular dynamics simulation method, the adhesion characteristics of asphalt ...
Effects of Physio-Chemical Factors on Asphalt Aging Behavior
Publisher: American Society of Civil Engineers
Abstract: Based on an accelerated asphalt-aging test in the laboratory, the authors evaluated the physical and chemical properties of asphalt at different aging times and temperatures for this paper. They evaluated the properties ...
Comprehensive Performance Evaluation and Cost Analysis of SBS-Modified Bioasphalt Binders and Mixtures
Publisher: American Society of Civil Engineers
Abstract: Developing new sustainable materials such as bioasphalt has become a research trend in recent years. In this study, bioasphalt modified with the addition of styrene-butadiene-styrene (SBS) was investigated to research ...
Characteristics of Latex-Modified Bitumen Prepared via Foaming Technique Using Water and Diluted Methanol
Publisher: ASCE
Abstract: The ability of latex to notably improve the performance of asphalt pavements has established the material as a favorable modifier in asphalt systems. However, the high viscosity of latex-modified asphalt (LMA) binders ...
Characterization of the Distress Modes and In Situ Material Properties of Highway Asphalt Pavement with Long Service Life
Publisher: American Society of Civil Engineers
Abstract: A 36-year-old, heavily trafficked highway asphalt pavement was analyzed in detail. The variation in structural capacity was assessed by a falling-weight deflectometer (FWD). Trenches were cut to examine the distresses in ...
